please help for mimaki cjv 30 -130

[kensign]

hi, i bought a mimaki cjv30-130 old,was working great for cutting ,but the print head is dry out. i try long time and finally got some test print out, then i took off the print head and clean it for a long time with strong pressure and solution and i knew i fried up the printhead board and even more, mainboard or sliding board. . I put the old leaking print head back after clean it , right away show up error code 06 and i turn the machine on and off couple of times trying as service says. Then the machine went into comma, control panel all dead, won't start up, no power up, no boot , no lights on inside the back all the mainboard ,nothing at all . I know i must have some solution or things on the print head board or leaking and blew it for sure. I knew that,But now only the one led light shows solid red on the slider board, and the button green light on and when press it has sound, so i assume the power board is still ok. , but not the mainboard, or sliding board. I disconnected the ribbons from the print head to the slider board or from the slider board to the main board, still nothing. . I check fuse f13, give reading 0.9. Is it blown? I am not good at electronic. Dont know how to touch and where to touch the tp1-tp4 or others.,but i could read ohms or voltages ,,please show me detail or circle them .
The last photo is my machine. Anyone could tell me where i check and how,,in details

thank you

Thank You.
I have done all the tps on the mainboard, From tp1 to tp 8.
yet, I got one test print tp3 very low, It's like zero. 0.00. Others are in the range between 17kohm - 18kohms
I haven't done any voltages check on mainboard or others. I believe the power board is still working. It has green on the power button and has click sound. I have found some one else has green on meant poer board is ok. just believe so now..
I don't know where the tp3 leads to , where is the broken part and what to fix,,.
As for the sliding board , it has a red led on when push the power button on the side, no power on the panel,I test all the tp6-tp13. and tp 10 give me reading 1, all others give 17 and under 18. here says 10 m ohm and more is good, less than is bad.
Also test pin CN3-5 to cn3-7, no 8 , over 14 k ohm, except cn3-8 has 3.23, I don't see anything broken by eyes, where should i look for or test. please help.
My f 13 375 mA fuse had reading 0.09 ohm
power board fuse seems not broken,,

I tested all transistors on the heat radiator you called. Yet , found 2 are not giving reading , zero. I will get them changed. But i have something to make sure, My defective transistors are A1742 (L02) and C4550 (k12). Other transistor have reading between 17 t0 18. or below. Now i wanna ask what kind of transistor should i be getting, I googled, says C4550 (
11y . NEC. A1742 (11 L02).. Is the other reading number matters and they are excatly fitted. Please give advise.
Also dont know where to go with slidering board. I tested as the book. says. One tp give zero, others about the same. Tp6-tp13
Tp 10 give zero.
Please help me .Thanks, you are the best guy ..
